Supports JPG, PNG, WebP, GIF, BMP, HEIC, AVIF - Max file size: 15MBCompressing your image...
Privacy / no-upload: This free image compressor runs entirely in your browser. Your JPG, PNG, WebP, HEIC, and AVIF files are not uploaded to our servers — HEIC/AVIF decoding and compression both happen on your device — you pick a quality preset, optionally resize, strip EXIF, preview the savings, and download. For a full metadata viewer (GPS-only strip + batch ZIP), try the EXIF remover. Prefer a deeper comparison? See our TinyPNG alternative (privacy / browser-only) guide, or the full list of best free client-side image tools (no upload).
Need a free image compressor that keeps photos looking sharp? This tool reduces JPG, PNG, WebP, and iPhone HEIC/AVIF file size so pages load faster, emails stay under attachment limits, and product galleries stop dragging. No install, no signup — choose a file, compress, download.
Whether you searched for an image compressor online, a free online image compressor, or a no-upload image compressor, you can dial quality with Max / Balanced / Web small presets, optionally resize, strip metadata, and see size savings before you save.
An image compressor lowers the number of bytes in a picture file while trying to keep visual quality. That usually means smarter encoding (JPEG/WebP quality settings), choosing a better format for the content, and sometimes resizing so the image isn’t larger than you display it. Smaller images mean faster sites, lower bandwidth, and better Core Web Vitals.
Our compressor uses HTML canvas in your browser: you control quality, output format, and optional max dimensions, then compare original vs compressed side by side.
Compress hero images, thumbnails, and inline photos before publishing so pages feel snappy on desktop and mobile.
Keep storefront galleries looking crisp while cutting file weight that slows category and product pages. After compressing, pad to square for marketplace listings, check print inches with the DPI converter, tile multi-up sheets with our catalog image tiler or follow the ecommerce catalog tiling guide, or split into an Instagram grid; clean camera filenames with the AI image renamer.
Compress drafts, client proofs, and personal photos without sending them through a third-party upload API. Shooting on iPhone? Drop the HEIC straight in — it decodes in your browser and compresses to a small JPEG (or PNG/WebP) with no convert-first step. Need a batch HEIC→JPG? Use HEIC to JPG.
Shrink attachments and creatives so they clear size limits and still look good in feeds and previews. For Instagram carousel grids, compress first, then split into a 3×3 (or custom) grid — both steps stay in your browser.
You can still drag the slider anywhere between 30–100%, pick JPEG / PNG / WebP output (or Auto), resize by percent or max width/height, and strip EXIF. Honest limit: one image at a time — multi-file batch compress is not supported yet.
A: Choose your image (or drag and drop it), pick a quality preset or slider value and optional resize settings, then click Compress Image. Preview the savings and download the smaller file instantly — no account required.
A: It depends on the quality setting and format. JPEG and WebP use lossy compression, so lower quality means smaller files with more compression artifacts. PNG is better for sharp graphics; try 70–85% quality for photos as a starting point, or use the Balanced preset.
A: This free image compressor supports JPG/JPEG, PNG, WebP, GIF, BMP, iPhone HEIC/HEIF, and AVIF (max 15MB). You can keep the original format or convert the output to JPEG, PNG, or WebP; HEIC and AVIF default to JPEG output.
A: Yes. You can compress images online for free with no registration, watermarks, or software install. Processing happens in your browser.
A: No. Compression runs locally in your browser using canvas processing. Your photos are not uploaded to our servers for this tool, which helps keep your files private — a no-upload alternative to typical TinyPNG-style compressors.
A: For most websites, aim for the smallest file that still looks sharp on screen. Many product and blog images work well under 200–500KB after resizing to the display width and compressing. Use WebP when browsers support it for even smaller files.
A: Max quality (~92) keeps photos looking nearly identical with modest size savings. Balanced (~80, default) is a strong everyday setting for web and ecommerce. Web small (~60) prioritizes file size for thumbnails, email, or slow connections — always preview before downloading.
A: Yes for privacy-minded users: this free image compressor processes files in your browser instead of uploading them to a compression API. For a side-by-side comparison, see our TinyPNG alternative (private browser compressor) guide.
A: Not yet — multi-file / batch compress is not supported. Compress one image at a time, download it, then repeat. Batch support may come later.
A: Anyone who needs lighter JPG, PNG, or WebP files without sending photos to a third-party server: bloggers, Shopify/Amazon sellers, freelancers, and developers optimizing Core Web Vitals. Pair it with our catalog image tiler or AI renamer for ecommerce workflows.
A: Yes. Drop an iPhone HEIC/HEIF or an AVIF straight into the compressor — it decodes in your browser (no upload, no separate conversion step), then compresses to JPEG, PNG, or WebP at your chosen quality. Auto output turns HEIC/AVIF into JPEG, the most compatible choice. Large iPhone photos take a few seconds to decode. Re-encoding drops HEIC metadata such as GPS location. (Batch HEIC→JPG? Use HEIC to JPG.)
A: Yes for most feeds: compress (and optionally resize) here so each cell stays light, then use the Image Splitter to cut the photo into a 2×2, 3×3, or custom grid with ZIP download — both tools run in your browser with no upload.
